Encapsulated underground duct work which was a transite concrete pipe with metal connectors and elbows that were heavily rusted out.
Encapsulated all underground asbestos transite air ducts with our duct lining material. The air in the home is now environmentally safe to breathe.
Televised ducts under slab floor. Ducts are PVC with metal connections and fittings that are rusting. Downspouts in back of house are run out but are not pitched so water is frozen in downspouts not allowing water to flow properly. Suggest reconfiguring downspouts so there is more pitch so water will not freeze in them. This will reduce the amount of water accumulating next to the house which causes water to enter into the ducts. Once the water issue is resolved the ducts should be spray lined with Duct Armor duct lining material.
Video inspection of underground air ducts. Ducts are metal and rusting. Suggest spray lining ducts with Duct Armor Duct lining material.
